Really! The mailroom is just like a modern computer on another scale!
In fact, the only real
difference between the mailroom and a real computer is that
a real computer might have dozens of hands (called
registers) and the memory might have millions of
mailboxes (called words).
Consequently, a pointer to
a word in a computer’s memory might need to be in
the billions and therefore you would need 4 bytes of
memory to store it.
